DENVER – Jason Oden got the start at running back Friday night for the CSU football team.

But Dee Hart and Treyous Jarrells took over the Rams' rushing attack in the season-opening game against the University of Colorado in Denver.

Hart, a graduate transfer from Alabama, ran for 139 yards and two touchdowns on 22 carries. Jarrells, a junior-college transfer, had 121 yards and one touchdown on 17 carries.

Oden, a converted safety, had just one carry for an 8-yard gain.

The last time a Colorado State University running back ran for more than 100 yards against CU was Leonard Mason in 2009. The last time two Rams went for more than 100 yards in the same game was in 2002 at Nevada, when quarterback Bradlee Van Pelt ran for 128 yards and running back Cecil Sapp went for 125.

SAMBRAILO HURT: The one returning starter on CSU's offensive line went down with a right knee injury early in the first quarter and didn't return.

Trainers helped senior left tackle Ty Sambrailo off the field and took him immediately to the locker room for further evaluation. Coach Jim McElwain said after the game that Sambrailo had suffered an injury to the medial collateral ligament that would sideline him for "about three weeks."

CSU gained 266 yards on the ground and allowed just one quarterback sack. The other four starters on the offensive line -- guards Fred Zerblis and Mason Myers, center Jake Bennett and tackle Sam Carlson -- were making their first career starts.

Sambrailo is the fourth CSU tackle to be sidelined with an injury already this year. Senior Mason Hathaway suffered a season-ending knee injury during the second week of fall camp. JC transfer Jordan Finley suffered a knee injury at the end of spring drills that required surgery and will miss at least the first four games of the season, McElwain said. Redshirt freshman Jordan Benson injured an ankle in practice two weeks ago and has not practiced since.

FIRST TDs: CU scored its first points of the season on a pass play for the seventh time in eight years. Six of those came against CSU. Nelson Spruce, who scored the Buffs' first TD of the season two years ago against CSU, caught a 54-yard pass from quarterback Sefo Liufau with 10:31 remaining in the first quarter to put CU on top 7-0.

CSU's first score of the season came on a running play for the first time since 2009. Hart ran for the score from 8 yards out with 2:39 remaining in the first half to cut the CU lead to 10-7.

CSU's first score the past two seasons had come on field goals by Jared Roberts.

CROWD COUNT: The season-opening game drew 63,363 fans, the most for a Rocky Mountain Showdown since 2008. The first four games CSU and CU played in Denver drew more than 73,000, with a high of 76,036 — the largest crowd ever for a college football game in the state.

CSU wound up selling just under 27,000 tickets to the game, including the entire allotment it set aside for students, senior associate athletic director Jason Layton said. CU sold more than 32,000, school spokesman Dave Plati said. The remaining tickets were purchased through the Denver Broncos ticket office.

COLORADO COUNT: CSU had 44 players on its season-opening roster from Colorado high schools, while CU had 23. Six of the Rams' starters were from Colorado, and only one CU starter was an instate product — defensive end Derek McCartney. The grandson of Hall of Fame Buffs coach Bill McCartney is a redshirt freshman from Faith Christian High School in Westminster.

Cartwright has been slowed by an ankle and foot injury that required offseason surgery and was listed as "questionable" on the Rams' injury report earlier in the week. His 22-yard pass reception to the CU 19-yard line set up CSU's first touchdown.
